I don't understand how V4 will help with anything. How using spare CPU cycles (which I don't have) is of any benefit to an average John.
I ran the TESTNET for over 2 weeks and still don't see the full picture.
I have an old gaming computer and I would rather use it for other purposes which means the CPU needs to be utilized for whatever application that I'm running needs. Along with the GPUs and other components.
First of all V4 stops dual mining, where miners just add mining of PascalCoin even it doesn't really pay off. Dual mining is harmful because it makes it unrealistic expensive to mine PascalCoin.
Next it stops asic mining and opens for cpu mining to make it more difficult to establish a monopoly.
It is nice of you to run a TESTNET node, but in my opinion you run too many nodes right now. It is a waste of electric power and even makes it difficult for other people to test things.
